Variant antigen diversity in Trypanosoma vivax is not driven by recombination [PDF]

Nature Communications, 2020
Trypanosoma rely on variant surface glycoprotein (VSG) to escape host immunity, but mechanisms generating antigenic diversity of VSG are poorly understood. Here, Silva-Pereira et al. show that T.
